We have the open CTI adapter working for lightning. I wanted to add a requirement where we have to make a callout to another system and check for DNC and based on the response we need to make the call. How i can achieve this just by clicking the phone number on salesforce?
I went to through some links but i am not getting clear idea on the implementation.

Please help me on achieving this fucntionality. I am not even sure whether it is possible.
